METALLIC SULPHIDES OCCUR IN QUARTZ-CALCITE VEINS AND DISSEMINATIONS IN THE COUNTRY ROCK OF NICOLA VOLCANICS AND SEDIMENTS OF TRIASSIC AGE. THESE STRATA ARE FOLDED AND AT SWAKUM MTN. THEY ARE IN A SOUTH-PLUNGING ANTICLINE WHOSE AXIS LIES CLOSE TO THE MTN. SUMMIT. A STRONG MAGNETIC ANOMALY AT THE PEAK MAY INDICATE A BURIED INTRUSIVE WHICH COULD HAVE BEEN THE SOURCE OF MINERALIZATION.
